as seen here http://vimeo.com/31561361. I found some documentation here http://algo.mur.at/projects/autoklavierspieler  but I'm having trouble finding out which solenoid to use. 

I tried to contact him directly but have had no luck. If anyone has any recommendations on where to get solenoids with similar secifications to Winfried's or where i can contact him, please let me know.
